Lee Min Jung shows off her singing voice once again and contributes a track to the “Wonderful Radio”soundtrack. The music video for the song “Write the Truth,” performed by Lee Min Jung is recently released.

The music video features Lee Min Jung performing the song as her character, Jina, who is a former idol singer from the fictional group Purple, but has since fallen out of fame and is now working as a radio DJ. Jina is instrumental in her producer’s (played by Lee Jung Jin) plan to retain just 4% of their listeners and stay on the air.

The actress has already contributed to a film soundtrack once. Together with Park Shin Hye, she sang a track for the soundtrack of 2010’s “Cyrano Dating Agency,” which she also starred in.
